A. LEMUEL ADAMS, OF NEW YORK, N. Y.

ROLLER AND EXTENSION AXLE.

SPECIFICATION forming part of Letters Patent No. 338,459, dated March23, 1886.

Application filed November 9, 1885.

To all whom it may concern.-

Be it known that 1', A. LEMUEL ADAMs, a citizen of the United States,and a resident of New York, in the county of ,New York and State of NewYork, haveinvented certain new and useful Improvements in Roller andExtension Axles, of which the following is a specification.

My invention relates to roller and extension axles for book-cases andother devices; and it consists in certain novel details of constructionand operation, as hereinafter more particularly described, andillustrated in the accompanying drawings, in which- Figure 1 is a sideView of my invention. Fig. 2 is a top or plan View. Fig. 3 is a sideView of my invention applied to a book-case.

Similar letters indicate similar parts.

The letter A designates bars of wood or iron, having their ends restingupon supports B B, so as to permit of their being moved laterally, andhaving their outer ends provided with a point, a, to retain them inposition; or after the bars A A are adjusted to their proper positionthey may be secured by screws n. Intermediate of the ends of bars A A, Iprovide axles O O by passing them through openings in the bars, whichaxles have a diameter smaller than said openings, so that the axles willmove freely therein,and so that the space between the bars may beincreased or diminished, as may be desired, by moving the bars laterallyon the axles. On the ends of the axles O O, I place rollers D D, whichextend above the top of the bars A A, and which turn freely on theiraxles, as shown in Fig. 1.

On one of the supports is secured by means of fastenings a a a anovel-shaped spring, E, which is first bent in the shape of a staple,then to the right and left, and then upward and outward, on the outerends of which I provide rollers b b, as shown in Figs. 1 and 2,

Serial No. 182,320. (No model.)

which spring by its peculiar construction assists in placing a book inits proper aperture. The spring E may be extended or contracted tocorrespond with the width of the position.

A series of my improvements may be constructed side by side withdivisions between them, forming pigeon-holes, like a book-case, whichholes may be of any suitable size.

The operation of my invention is as follows: When a book is to be placedin position, it is first rested on the spring-rollers b b of the springE, which by its own inherent elasticity assists in forcing the book ontothe rollers D D, when the book is easily passed by means of said rollersD D to its proper place.

The spring E is an important feature of my invention, as it may beapplied to the lids of match, tobacco, and other boxes to open them,andfor other purposes.

Vhat I claim as new, and desire to secure by Letters Patent, is

1. A book-rack consisting of the bars A,

.axles O, rollers D, and spring E, substantially as herein shown anddescribed.

2. A spring, E, bent in the shape of astaple, then to the right andleft, then upward and outward, with or without rollers on its outerends, substantially as shown and described.

3. In combination with a book-rack, the spring E and its rollers 12,substantially as and for the purpose described.

4. A book rack consisting of the bars A, axles O, rollers D, spring E,and rollers b, substantially as and for the purpose described.

Signed at New York, in the county of New York and State of New York,this 6th day of November, A. D. 1885.

A. LEMUEL ADAMS.
